FIELD OF INVENTION

The present invention is generally related to a towing apparatus and,more particularly, to an under bed hitch mounting system.

BACKGROUND

Many vehicles are designed to transport freight, goods, merchandise,personal property, and other such cargo. An operator often utilizes ahitch assembly to connect a towed vehicle to a towing vehicle, e.g.,connecting a trailer to a pick-up truck, to increase the capacity totransport the cargo. Many types of coupling devices have been developedfor providing this connection between towing and towed vehicles.

It is well known to utilize a hitch to connect a towed vehicle to atowing vehicle. There are many different types of hitches that may beattached to the towing vehicle in a variety of ways, depending on thetype of hitch used. For example, some fifth wheel hitches mount to theframe underneath the bed of the pickup truck while other fifth wheelhitches mount to an above bed mounting system.

Traditional fifth wheel hitches include a head assembly for receiving aking pin on a towed vehicle, a base having a plurality of legs, and oneor more mounting rails. In some systems, the legs of the fifth wheelhitch are designed to be secured to mounting rails that are attachedabove the bed or on the bed of the towing vehicle. In other systems, themounting rails may be fixed to the frame of a vehicle underneath thebed. For example, the mounting rails may be connected between twoportions of a pickup truck frame underneath the truck bed. The mountingrails may include a plurality of apertures for receiving the legs of thefifth wheel hitch.

Corresponding openings may be cut in the truck bed and aligned with theapertures in the mounting rails. The legs of the fifth wheel hitch maybe connected to apertures in the mounting rails through the openings inthe truck bed, thereby securing the fifth wheel hitch to the frame ofthe vehicle. When the fifth wheel hitch is not in use, the legs may bedisconnected from the apertures in the rails and the hitch may beremoved from the bed of the truck. Caps may be placed over the aperturesto allow the truck bed to be used for other purposes.

Traditional gooseneck hitches may also mount to a towing vehicle framebeneath the load bed of the towing vehicle. A gooseneck hitch may bedesigned for use in a load bed of a towing vehicle similar to a fifthwheel hitch. The difference is that the gooseneck uses a ball andcoupler verses a kingpin and pin receiver. Gooseneck hitches may includea mounting plate configured to connect to the frame of the towingvehicle, a receptacle in the mounting plate configured to receive a ballhitch, and a hitch ball removably connected to the receptacle andconfigured to engage a coupling member of the towed vehicle. An openingin the load bed of the towing vehicle may be aligned with the receptaclein the mounting plate. This may allow the hitch ball to connect to thereceptacle through the opening in the load bed of the towing vehicle.The hitch balls themselves are typically removable or retractable sothat when the hitch is not in use, the hitch ball may be removed orretracted when not in use. This may generally prevent obstruction of theload bed of the towing vehicle.

Towing vehicles are generally arranged to accommodate either a fifthwheel hitch or a gooseneck hitch, but not both. To convert a towingvehicle from accommodating a fifth wheel hitch to a gooseneck hitch orvice versa is time and labor intensive and inefficient. However, sincefifth wheel hitches and gooseneck hitches use different mountingconfigurations, traditionally only one hitch can occupy this location.Therefore, there is a need in the art for an improved apparatus fortowing vehicles that may allow for selectively accommodating either afifth wheel hitch or a gooseneck hitch.

Additionally, because the mounting rails attach to the underside of thetowing vehicle, there may be significant space limitations. These spacelimitations may cause limitations in the mounting rails that may beused. This in turn may impact the ability to attach mounting rails tothe underside of the towing vehicle, including, without limitation tothe frame of the towing vehicle. Therefore, there is a need in the artfor improved mounting rails.

DETAILED DESCRIPTION

Reference will now be made in detail to exemplary embodiments of thepresent invention, examples of which are illustrated in the accompanyingdrawings. It is to be understood that other embodiments may be utilizedand structural and functional changes may be made without departing fromthe respective scope of the invention. Moreover, features of the variousembodiments may be combined or altered without departing from the scopeof the invention. As such, the following description is presented by wayof illustration only and should not limit in any way the variousalternatives and modifications that may be made to the illustratedembodiments and still be within the spirit and scope of the invention.

FIGS. 1-2 illustrate some embodiments of a hitch mounting system 30,such as an under bed hitch mounting system 30 shown in the exemplaryembodiments described and shown herein. The under bed hitch mountingsystem 30 may be used with a towing vehicle 34 and may allow forselectively accommodating both of a fifth wheel hitch 91 and a gooseneckhitch ball 448. Although, in other embodiments, the hitch mountingsystem 30 may only allow for having attached thereto fifth wheel hitchesand yet other embodiments the hitch mounting system 30 may only allowfor having attached thereto gooseneck hitches.

Many types of gooseneck and fifth wheel hitches may be mounted to a loadbed 32 of a towing vehicle 34. These types of hitches may often have atleast a portion thereof mounted beneath the load bed 32 of the towingvehicle 34 in conjunction with the towing vehicle's own frame rails 36;exemplary embodiments of which are described in more detail below.

The under bed hitch mounting system 30 may include at least one railmount or transverse member 40 and may include at least one mid rail oradapter plate 45 secured to the rail 40. By way of a non-limitingexample, the under bed hitch mounting system 30 may include two rails 40and one mid rail or adapter plate 45. The rails 40 and adapter plate 45may be configured to support a gooseneck hitch ball 448 or a fifth wheelhitch 91, as applicable. While the under bed hitch mounting system 30may be shown and described as having two rails 40 and one mid rail oradapter plate 45, it is to be understood that there may be anyappropriate number of rails and adapter plates and it should not belimited to that shown and described herein. By way of a non-limitingexample, the under bed hitch mounting system 30 may only include tworails 40 and may not include the adapter plate 45.

The rails 40 may be of any appropriate shape or size, such as having agenerally tubular, square, rectangular, or the like shape, and may besized to generally fit under the load bed 32 of the towing vehicle 34.More specifically, the rails 40 may be attached to the frame rails 36 ofthe towing vehicle 34. In some embodiments, the rails 40 may be formedfrom a single generally continuous piece, such as a generally continuousand generally rectangularly-shaped tubular member. The shape of therails 40 may allow the rails 40 to have the ability to fit between theframe rails 36 of the towing vehicle 34 and the load bed 32 of thetowing vehicle 34, which may be a generally constrained area. The rails40 may be made from rigid material such as steel or the like. The rails40 may include a top surface 42 and a bottom surface 44. The rails 40may also include a first end 50 and a second end 55. The first andsecond ends 50, 55 may each include a deformed portion 57, 59respectively, which may be generally positioned on the bottom surface44.

The deformed portions 57, 59 may allow the rails 40 to generally fitbetween the frame rails 36 of the towing vehicle 34 and the load bed 32of the towing vehicle 34. The deformed portions 57, 59 may be deformedin any appropriate manner. By way of a non-limiting example, thedeformed portions 57, 59 may be formed by stamping, which may create agenerally smooth, reinforced, tubular structure that may be capable ofattaching to the towing vehicle 34.

The deformed portions 57, 59 may be of any appropriate shape and size.The shape and size may be based on the configuration of the towingvehicle 34 to which the under bed hitch mounting system 30 may beattached. In some embodiments, the deformed portions 57, 59 may be ofgenerally the same shape and size. In other embodiments, the deformedportions 57, 59 may be of generally different shapes. The appropriateshape may depend upon the shape and size of the frame rails 36 of thetowing vehicle 34 and the space between the frame 36 and load bed 32 ofthe towing vehicle 34.

In some embodiments, the deformed portions 57, 59 may include top bottomsides 60, 61 that may be generally folded up toward the top surface 42.This may generally form a substantially C-shape as shown in FIGS. 3-5.The folding of the deformed portions 57, 59 may form channels 65, 67,respectively. More specifically, and as shown in FIGS. 3-5, the rails 40in some embodiments may transition from a generally full, undeformedtubular portion, to a generally C-shaped portion through first andsecond transition portions 68, 69, which may be positioned at the firstand second ends 50, 55 of the rails 40.

Unlike the prior art, no additional rail components may be required toattach the rails 40 to the frame rails 36 of the towing vehicle 34. Therails 40 being of a generally single continuous member may generallyprevent some of the structural limitations of the prior art thatutilizes multiple pieces coupled together. The rails 40 of the presentteachings may generally limit the presence of stress risers, which maybe present in the rails of the prior art. The limitation or generalreduction of the unwanted stress risers may generally improve thefunction of the rails 40.

The under bed hitch mounting system 30 may further include a bracket 70,which may be generally L-shaped, and a plate 71, which may be generallyflat. The shape and size of the bracket 70 and plate 71 may be of anyappropriate shape and size and may vary depending upon the make andmodel of the towing vehicle 34 to which they may be attached. The rails40 may attach to the frame rails 36 of the towing vehicle 34 immediatelyunder the load bed of the towing vehicle 34 by attaching the brackets 70to the frame rails 36 of the towing vehicle 34. By way of a non-limitingexample, the brackets 70 may be attached to the frame rails 36 of thetowing vehicle 34 by welding, using fasteners such as nuts and bolts, orutilizing any other appropriate attachment apparatus or method.

The plate 71 may attached to the end portion 50, 55 of the rails 40 atthe deformed portions 57, 59 by any appropriate manner, such as by wayof a non-limiting example, welding, using fasteners such as nuts andbolts, or utilizing any other appropriate attachment apparatus ormethod. The thickness T of the plate 71 may generally allow for theappropriate spacing between the ends 50, 55 of the rails 40 and bracket70 to generally accommodate the space constraints present on theunderside of the towing vehicle 34. The attached combination of the flatplate 71 and the rails 40 may then be attached to the bracket 70. Insome embodiments, a fastener 72 may used to attach the attachedcombination of the plate 71 and the rails 40 to the bracket 70. In theseembodiments, the substantially C-shaped deformed portions 57, 59 maypermit adequate space for attachment of the fastener 72.

Each rail 40 may include one or more sockets 73. In some embodiments,each rail 40 may include a pair of sockets 73. However, in otherembodiments, the rails 40 may include any appropriate number of sockets73. The sockets 73 may be of any appropriate shape or size, such as agenerally ovular, circular or rectangular shape. The sockets 73 may beformed in the rail 40 in any appropriate manner, such as by way of anon-limiting example by piercing the rails 40 in an appropriatelocation. The sockets 73 may be configured to receive and support legs83 of the fifth wheel hitch 91. The legs 83 may be secured to the rails40 through the sockets 73 by any appropriate means, such as byfasteners, fastening systems, welding, or the like. Apertures 75 may bedrilled or otherwise formed in the load bed 32 of the towing vehicle 34that may generally correspond to the locations of the sockets 73 in therails 40 that may be attached to the frame rails 36 of the towingvehicle 34. The fifth wheel hitch 91 may be removably connected to thesockets 73 in the rails 40 through the apertures 75 located in the loadbed 32 of the towing vehicle 34 as further described herein.

In some embodiments, the sockets 73 may be shaped to attach a receivingmember 74 thereto. The receiving members 74 may selectively attach thelegs 83 of the fifth wheel hitch 91 to the under bed hitch mountingsystem 30. In these embodiments, the receiving members 74 may be mountedin the socket 73 provided in any of the rails 40. The receiving member74 may be secured in the socket 73 by any appropriate means, such aswith fasteners, welding or the like. In the some embodiments, thereceiving members 74 may be welded to the sockets 73.

In some embodiments, the receiving members 74 may compromise a puckmounting system of a fifth wheel hitch 91 whereby the fifth wheel hitch91 may be installed through four small apertures 75 in the load bed 32,such as that disclosed in U.S. Patent Application Publication No.20100109285, entitled “UNDERBED HITCH MOUNTING SYSTEM,” and thatdisclosed in U.S. Pat. No. 7,121,573, entitled “VEHICLE ACCESSORYMOUNTING SYSTEM,” the disclosures of which are incorporated by referenceherein. Utilizing a puck mounting system or the receiving member 74 mayprovide generally uninhibited use of the load bed 32 of the towingvehicle 34 when the fifth wheel hitch 91 is dismounted. The receivingmember 74 may be of any appropriate shape or size, such as by way of anon-limiting example, a cylindrical, oval, or a square shape, but shouldnot be limited to that shown and described herein.

As shown in FIG. 6, the receiving member 74 may include a channel member76 and a puck member 78. The channel member 76 may be shaped to fitwithin the sockets 73 such that it has a top surface 77 flush orsubstantially flush with the top surface 42 of the rails 40. The channelmembers 76 may then be welded to the top surface 42 of the rails 40.This may permit attachment of the receiving member 74 to the rails 40without having to access the underside of the load bed 32 of the towingvehicle 34 as may be required in the prior art. This may make attachingthe receiving members 74 to the rails 40 generally easier to accomplish.

The channel member 76 shown in FIGS. 6-7 may include a pair of legs 84that may be of a shape and size to generally permit the channel member76 to fit within the socket 73 so that the top surface 77 of the channelmember 76 may be generally flush or substantially flush with the topsurface 42 of the rails 40. The channel member 76 may, however, notinclude the legs 84. If the depth of the sockets 73 in the rails 40 isless, the legs 84 may not be necessary. If, on the other hand, the depthof the sockets 73 in the rails is greater it may be necessary to includethe legs 84.

In some embodiments, the channel member 76 may include a plurality ofbolt apertures 88 and a pair of locator apertures 92. The puck member 78may include a pair of nubs 94, a plurality of bolt apertures 96 and acenter section recess 98, such as an aperture or slot. The nubs 94 ofthe puck member 78 may engage with the locator apertures 88 of thechannel member 76 so that the puck member 78 may be generally orientedin the proper position on the channel member 76 during installation.Further, the engaging of the nubs 94 with the locator apertures 92 mayposition the bolt apertures 88 of the channel members 76 with the boltapertures 96 of the puck member 78. A fastener 97 of any appropriateshape and size may then be inserted into the bolt apertures 96 and 88 sothat the puck member 78 may attach to the channel member 76.

The puck member 78 may be of a size and shape so that it may generallyfit flush or substantially flush with the load bed 32 of the towingvehicle 34 in which it may be installed. Different thickness puckmembers 78 may be used to account for the varying thicknesses of loadbeds of various towing vehicles, i.e., the puck member 78 may be of anappropriate thickness based upon the distance between the load bed 32and the frame rails 36 of the particular towing vehicle 34 to which theunder bed hitch mounting system 30 may attach. Additionally, the puckmember 78 may have a thickness that may generally account for a bedliner installed onto the load bed 32 of the towing vehicle 34 so thatthe puck member 78 may generally remain flush or substantially flushwith the bed liner.

The center recessed section 98 may be of a shape and size to receive anaccessory member 101 such as a T-bolt 103 having a handle 105. Anynumber or variety of accessory members 101 may be utilized with thereceiving members 74. The accessory member 101 may be any appropriate ordesired type of object, such as a cap, a safety chain tie down member,fifth wheel hitch or the like. By way of a non-limiting example, capsmay be placed over the receiving members 74 or apertures 75 in the loadbed 32 when the fifth wheel hitch 91 is not in use. In theseembodiments, the accessory member 101 may also attach the legs 83 of thefifth wheel hitch 91 to the rails 40. The fifth wheel hitch 91 may bepositioned onto the load bed 32 of the towing vehicle 34 so that thelegs 83 may generally align with the sockets 73 and in particular thereceiving members 74. The appropriate accessory member 101 may then beinserted into the receiving members 74. The accessory member 101 maythen be rotated to secure the appropriate items, such as by way of anon-limiting example; legs 83 of the fifth wheel hitch 91 to the rails40. In particular, the handle 105 may only need to be turned one-quarterrevolution and then the T-bolt 110 may engage the receiving member 74 tosecure the legs 83 of the fifth wheel hitch 91 to the receiving member74 of the rails 40. It should be understood, however, that any type ofaccessory member can be used and is not limited to that shown ordescribed herein.

Additional embodiments of an under bed hitch mounting system accordingthe present teachings are described below. In the descriptions, all ofthe details and components may not be fully described or shown. Rather,the features or components are described and, in some instances,differences with the above-described embodiments may be pointed out.Moreover, it should be appreciated that these additional embodiments mayinclude elements or components utilized in the above-describedembodiments although not shown or described. Thus, the descriptions ofthese additional embodiments are merely exemplary and not all-inclusivenor exclusive. Moreover, it should be appreciated that the features,components, elements and functionalities of the various embodiments maybe combined or altered to achieve a desired under bed hitch mountingsystem without departing from the spirit and scope of the presentteachings.

In other embodiments shown in FIGS. 9-10, the receiving member 174 mayinclude a channel member 176 and a puck member 178. The receiving member174 or more specifically, the channel member 176 may include a pair oflegs 184 that may be of a shape and size to permit the channel member176 to generally fit within the socket 73 so that a top surface 186 ofthe channel member 176 may be flush or substantially flush with the topsurface 42 of the rails 40. It, however, is not necessary to include thelegs 184 depending upon the size and shape of the rails 40 and thethickness of the channel member 176 as previously mentioned.

The channel member 176 may further include a pair of locator apertures192 and a threaded portion 185. The puck member 178 may include ananti-rotation mechanism 193 such as a locking pin 197 as shown in FIG.10, a male-threaded portion 195 and a center section recess 198. Inthese embodiments, the puck member 178 may be attached to the channelmember 176 by engaging the threads 195 of the puck member 178 with thethreads 185 of the channel member 178. The threads 185 may matinglyengage the threads 195, which may secure the puck member 178 to thechannel member 176.

To ensure that the puck member 178 is not easily removed from thechannel member 176, an anti-rotation mechanism 193 may be used. In theseembodiments, the anti-rotation member may include a locking pin 197 anda corresponding aperture 199 in the puck member 178. The locking pin 197may fit into the aperture 199 via an interference fit. The locking pin197 may be pushed into the aperture 199. Next, the puck member 178 maybe rotated until fully seated and then rotated in an opposite directionuntil the locking pin 197 may engage the locator aperture 192. Once thelocking pin 197 may be so engaged with the locator aperture 192, thelocking pin 197 may be pushed into engagement with the locator aperture192 via the interference fit. The anti-rotation mechanism 193 maygenerally prevent further rotation and thus removal of the puck 178 fromthe channel member 176.

The center recess section 198 may be of a shape and size to receive anyappropriate accessory member 101 such as the T-bolt 103 having a handle105. Any number or variety of accessory members 101 may be utilized withthe receiving members 174.

In other embodiments shown in FIG. 11, a receiving member 274 may be ofa one-piece integral construction. In these embodiments, the receivingmember 274 may include a channel portion 276 and a puck portion 278,which may be integrally formed with one another. The channel portion 276may include a pair of legs 284, which may be optional as previouslydiscussed. The legs 284 may be of a shape and size to permit the channelportion 276 to fit within the socket 73 so that a top surface 286 of thechannel portion 276 may be flush or generally flush with the top surface42 of the rails 40. It, however, is not necessary to include the legs284 depending upon the size and shape of the rails 40 and the thicknessof the channel portion 276.

The receiving member 274 may be formed by casting, forging, or any otherappropriate process. As the receiving member 274 may be integrallyformed, the receiving member 274 may not require any kind of mechanismto ensure that the channel portion 276 and puck portion 278 are alignedproperly as they may be formed generally properly aligned.

The center recess section 298 may be of a shape and size to receive anaccessory member 101 such as a T-bolt 103 having a handle 105. Anynumber or variety of accessory members 101 may be utilized with thereceiving members 274. The accessory member 101 may be any appropriateor desired type of object, such as a cap or a safety chain tie downmember.

In other embodiments in FIG. 12, a receiving member 374 may include anattachment portion 376 and a puck portion 378. Similar to the previouslymentioned embodiments, the receiving member 374 may be a one-pieceintegrally formed body. The receiving member 374 may be formed byforging, casting or any other appropriate method. The attachment portion378 may include a pair of flanges 381 and a pair of locating apertures392. The flanges 381 may be substantially flat and may cause theattachment portion 378 to be a substantially oval shape having a firstend portion 393 and a second end portion 394. In these embodiments,attachment portion 378 may be placed on the top surface 42 of the rails40 over the sockets 73. The attachment portion 378 may then be welded tothe top surface 42 of the rails 40. More specifically, the circumferenceof the attachment portion 378, less the first end portion 393 and thesecond portion 394, may be welded to the top surface 42 of the rails 40.The first and second end portions 393, 394 may not be welded to allowfor some flexibility in the receiving member 374. Having the flexibilitymay generally prevent or limit unwanted stress risers and strain on thereceiving member 374 and the rails 40. The locating apertures 392 may beused during the manufacturing process to help orient the center sectionrecess 398 that may be located in the puck portion 378.

In other embodiments, the attachment portion 378 may be attached to therail 40 along any location accessible via the load bed 32 of the towingvehicle 34. It may not be necessary to use the sockets 73 to attach thereceiving member 374 in these embodiments. The attachment portion 378may be welded to the top surface 42 of the rails 40. This structure maytake loading away from the rails 40.

The center recess section 398 may be of a shape and size to receive anaccessory member 101 such as a T-bolt 103 having a handle 105. Anynumber or variety of accessory members 101 may be utilized with thereceiving members 374. The accessory member 101 may be any appropriateor desired type of object, such as a cap or a safety chain tie downmember.

In those embodiments that may utilize the gooseneck hitch ball 448, theunder bed hitch mounting system 30 may utilize the mid rail or adapter45; exemplary embodiments of which are shown in FIGS. 13-16.
